FAA Private Pilot Airplane (PAR)Aerodynamics and Aircraft SystemsEasy
A pilot is planning a cross-country flight and reviews the aircraft's weight and balance. The maximum allowable takeoff weight is 2,300 lbs, and the maximum landing weight is 2,000 lbs. The planned takeoff weight is 2,200 lbs, with a planned fuel burn of 150 lbs during the flight. Will the aircraft be within landing weight limits?
- AYes, the landing weight will be 2,000 lbs, exactly at the limit.
- BYes, the landing weight will be 2,050 lbs, within the limit.
- CNo, the landing weight will be 2,150 lbs, exceeding the limit.
- DNo, the landing weight will be 2,200 lbs, exceeding the limit.
Show answer & explanationAnswer & explanation
Correct answer: B. Yes, the landing weight will be 2,050 lbs, within the limit.
To determine the landing weight, subtract the planned fuel burn from the takeoff weight. Planned takeoff weight is 2,200 lbs, and planned fuel burn is 150 lbs. Therefore, 2,200 lbs - 150 lbs = 2,050 lbs. This is within the maximum landing weight of 2,000 lbs, as 2,050 lbs is greater than 2,000 lbs.
Why the other options are wrong
- A. Incorrect calculation. The calculation shows 2,050 lbs, not 2,000 lbs.
- C. Incorrect calculation. 2,150 lbs would be the result of a 50 lbs fuel burn, not 150 lbs.
- D. Incorrect calculation. 2,200 lbs is the takeoff weight, not the landing weight after fuel burn.
Landing Weight Calculation
The process of determining the aircraft's weight at the point of landing by subtracting the estimated fuel burn from the takeoff weight.
- Must not exceed the maximum allowable landing weight.
- Fuel consumption is a primary factor.
- Ensures structural integrity during landing.
